Well, lowering a car that much with near OEM rate springs and near OEM dampers means you'll be spending a lot of time on the bump stops if you push it, hence
it's a bit rough on the road, but that's the price you pay for go-kart level handling.
Not the best for track use either. You can do a lot better if actual performance is your goal.
Stiff
≠ good. A good suspension will be compliant and still handle well. That means springs that are uprated from OEM and dampers that can control them. You don't really want it too stiff or you'll be lifting a wheel in the corners....:surprise:
If most of your time is daily driving, something like H&Rs or Vogtlands will probably be a better choice. They don't lower as much as the CS springs and ride better.
Get decent dampers, don't skimp on the important stuff. Koni Yellows might be ok for the track but not so much on the street. Koni FSDs ride a lot better and perform very well.
As to the sway bar, many here seem to like the Progress rear bar. There have been issues with the CS bar lately on newer cars (there is a discussion elsewhere on the forum) that has yet to be resolved.
End links should be replaced with adjustable units. Lowering the car changes the suspension geometry and the end links need to be shorter to correct that. Also, the stock endlinks have been known to fail when used with larger bars. HardRace sells them, and there is a vendor on Ebay (German Racing Parts) that sells good ones somewhat cheaper. The GRP links are built for the apocalypse....:smile2:
